Answer 1

It would help if you gave more detail about what you’re trying to do, however you can try this:

First make any variables you want to access in your aspx markup protected.

Then in the page_load method, call DataBind();

Then in your markup you can do this:

<%# VariableName %>

The “<%=” sequence can only be used within certain contexts in server controls. The sequence “<%#” is for DataBound controls and can be used in any context in ASPX page markup. Calling DataBind(); allows you to use this (almost) anywhere on the page.
